Abstract: A method for detecting infestation of grain-damaging insects in grain stored in a storage facility. This method comprises a first step of placing an insect trapping device that traps grain-damaging insects in the storage facility and leaving the device in the storage facility for a predetermined length of time, and a second step of detecting infestation of grain-damaging insects in the grain on the basis of how many grain-damaging insects have been trapped in the insect trapping device after the first step. The insect trapping device has a base that is impermeable to water or oil, a porous substrate that is disposed on one side of the base and is capable of holding water or oil, and water or oil held in the porous substrate.
